The red curvy patterns on the blade is painted using a normal sharp tip marker.

Spilled over red paint is cleaned off using cotton swab soaked with paint thinner.Light and swift is the way to go with the cotton swap since the thinner also dissolves the silver paint, which is something that must be avoided.

The completed 龍焔刀, with panel lines added to the entire part.The handle is supposedly black in color, but I don't want to paint it since it's very likely that the paint would be rubbed off by the model's hand when it's equipped to it. ^^;

The hollow points on either side of the cross-guard looks a bit too bland. ^^;

From the manual, the hollow spots are not used in any way at all. Mounting the sword to the backpack or weapon effect part uses the peg behind the cross-guard instead.

Since the hollow spots are not going to be used for any weapon gimmick, they can be enhanced using extra parts to make their appearance a little bit more interesting. ^^ The best and also simple-to-do accessories would be round jewels, which are really common features on most real or fictitious swords. ^^

The round mono-eye pieces are the largest parts on the runner, but there are also eight pairs of dual-eyes for Gundam-type model kits. Obviously, this option runner isn't meant specifically for Gundam model kits, and the purposes of the parts go beyond just as eyes on robots. The round parts seem very suitable as targeting scope on weapons as well. In Tenshouryu Koumei Nu Gundam's case, The smallest pair of round parts seem most suitable as jewels on the sword's cross-guard. ^^

Lucky me, the smallest type on the runner is a perfect match for the hollow spot. ^^No extra work of sanding the parts smaller would be needed then. ^^

Added the round parts onto the cross-guard.Plastic cement is used to secure the connection. ^^
